She added, “This is absolutely harmful to anyone who is easily influenced by societal pressures put on us from the diet culture to constantly be losing weight in a world that teaches us to equate our value and worth with the way we look and especially anyone in recovery from an eating disorder.”

Lovato also took issue with Instagram allowing this on her feed, writing, “Please Instagram, keep this bulls**t off mine and other’s feeds who could be easily effected by this disgusting advertisement.”

She added, “With how aware people are becoming of mental health and mental illnesses, I expect you guys to know better by allowing this advertisement to be allowed on your app. And shame on the game.”

Lovato has previously spoken about how Instagram contributed to her struggles with food, saying, “I was on Instagram and I started comparing myself to these Instagram models and I just thought to myself, someone needs to show my fans and anybody that’s looking at my account that what you see isn’t always what’s real.”

She added, “And so, I decided to embrace my flaws and—I don’t even like to call them flaws, it’s just a part of who I am—and show the world that I’m imperfect, but that’s what makes me beautiful.”

She has said that the constant reinforcement of a body she couldn’t have has made her accept herself for exactly who she is and not care about people’s opinions. (Image source: Instagram/Demi Lovato)
